Add freerdp backend

[LDprg]

This moved from #30 to here for better way of working.

[LDprg]

So I think generally the the base is finished and ready for merge. Just waiting for some reviews.

Maybe we want to change to command names (later this would we much more complicated).

[oskardotglobal]

Looks great.

We could just keep what you've called app as manual, but imo run would be better

@oskardotglobal did you try and build this branch ? Or should I test it on my side ?

[oskardotglobal]

Nope, I'll test this later

[AkechiShiro]

I tested the build works, but there are a few issues, I noticed @LDprg

• winapps-cli check
• I tried a few commands, but they seemed to fail if XDG_CONFIG_HOME wasn't defined, we should automatically fallback on $HOME/.config, this line needs to change : https://github.com/winapps-org/winapps/pull/42/files#diff-0431873891bc91ae27bf34f83bf089ab5eae92439517b2a088260a33cc1d359eR45

[oskardotglobal]

@AkechiShiro the latter is included in #26

[LDprg]

@AkechiShiro The first one is that winapps doesnt disable the freerdp output (which contains alot of unnecessary warings). I will investigate into this.

[LDprg]

@AkechiShiro did you test it with the generated quickemu from #26? I am not sure if we need a port forwarding from the guest to host to make rdp communication working per default.

[AkechiShiro]

@LDprg no I removed all the previous files to test cleanly but I understand that there is no quickemu get and VMs files

[oskardotglobal]

@LDprg I'll test it

[LDprg]

So finally I fixed the log outputs of freerdp causing unessecary warnings to be shown. Later we could redirect its output to some log files, however this will be in a sperate PR (just want this get through as fast as possible).

Furthermore I fixed some minor issues after the merge of #26 and renamed the app command to run.
@oskardotglobal can you review this again so I can merge.

[oskardotglobal]

Looks good otherwise

[LDprg]

@oskardotglobal I removed it.

[oskardotglobal]

Looks good.
